Cyanide
ASTM D7511-09 Standard Test Method for Total Cyanide by Segmented Flow Injection Analysis, In-Line Ultraviolet Digestion and Amperometric Detection This is a new standard test method that was developed by ASTM Committee D19 on Water to determine the concentration of total cyanide in drinking and surface waters, domestic wastewater, and industrial wastewater. Cyanide ion (CN-), hydrogen [...]
A Case for Laboratory Operators Using a Technical Support Contact as the First Step in Troubleshooting Many, if not most autoanalyzer and many other flow based instrument issues can be averted by operators utilizing a technical support contact at the very first sign of trouble. This recent case study clearly demonstrates the importance of why [...]
ASTM D7237 Standard Test Method for Free Cyanide with Flow Injection Analysis (FIA) Utilizing Gas Diffusion Separation and Amperometric Detection This is a new standard test method that was developed by ASTM Committee D19 to determine the concentration of free cyanide in an aqueous wastewater or effluents. The method detects free cyanide (HCN and CN-) and a [...]
ASTM D6888-09 Standard Test Method for Available Cyanide with Ligand Displacement and Flow Injection Analysis (FIA) Utilizing Gas Diffusion Separation and Amperometric Detection ASTM Committee D19 on Water has recently revised this standard. This method is used to determine the concentration of available inorganic cyanide in an aqueous wastewater or effluent. The method detects free [...]
Docket ID No. OW-2003-0070 Comments Related to the Proposed Cyanide Determination Methods Federal Register / Vol. 69, No. 66 / April 6, 2004 / Proposed Rules, pp. 18166 – 18226 Prepared by: Emil Milosavljevic, Ph.D. and Ljiljana Solujic, Ph.D. Distillation-based methods for determination of operationally defined cyanide have very limited application because of the serious interferences from the species likely [...]
Gas diffusion modules are used in autoanalyzers whether segmented flow analysis (SFA), sometimes referred to as continuous flow analysis (CFA), or flow injection analysis (FIA). The purpose of the gas diffusion module is to function as an in-line cleanup eliminating particulates, potential ionic interferences and chemical complexes. The target analyte permeates through the membrane into a [...]
Standard curves and check standards can make all the difference in the successful operation of autoanalyzers and discrete anlayzers. The importance of validating results for accuracy becomes a very important rock of consistency when operating an autoanalyzer or discrete analyzer in the hazardous field laboratory analysis environment. We are taught how to make standards and validate them with [...]
